INSECTICIDE.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed April 9, 1904. Serial No. 202,358.

To all whom it may concern.-

Be it known that I, W'ILLIs EUGENE EVER- ETTE, acitizen of the UnitedStates, and aresident of Tacoma, in the county of Pierce and State ofWashington, have invented certain new and useful Improvements inInsecticides, of which the following is a specification.

The object of my invention is to provide a thoroughly safe and effectivecomposition which when applied to fruit-trees, growing vegetables, andflowers will effectually destroy insects, caterpillars, worms, and theireggs, fungus growth, and other hurtful pests which attack such trees andplants.

To make this compound, I pulverize about one pound of each of thefollowing ingredients: sulfur, resin of pine, soap-powder, sodium oxid,tobacco-stems, Castor-oil beans, and pyrethrum-flowers, and add aboutone pound of asphalt-petroleum, about one pound of fumingsulfuric acid,and about one pound of commercial phenic alcohol, (carbolic acid.) Byasphalt-petroleum I mean that class of petroleum which has an asphaltbase in distinction from that which has a paraffin base or residue.Crude petroleum-oil with aparaffin base is the kind chiefly used in themanufacture of gasolene, kerosene, &c. When these lighter oils aredistilled off, a paraflin residue remains. Crude petroleum-oil with anasphalt base is that chiefly used to sprinkle dusty roads, because whenthe lighter oils haveevaporated away the asphalt will combine with thedust and form a hard road, whereas if the other kind were used theparaffin residue would gradually crumble into powder and blow away withthe dust. For this reason in my insecticide I prefer theasphalt-petroleum, because the residue tends to harden on the plant andform a protective covering for it. These ingredients are to be mixed tothe condition of a dough-like mass or paste and preferably divided intosmall portions-say about one-ou nce packages. To preserve these packagesfrom the air, they are preferably wrapped in paraffin-paper andtin-foil.

In using this compound for the purposes intended one ounce is to bediluted with about a gallon of boiling water and then sprayed upon theinsect-infested tree or vine. For hop-lice and when used with fruits andvegetables generally a weaker solution will suffice-namely, one ounce ofthe compound dissolved in from three to ten gallons of boiling water. Iusually cool the mixture to about Fahrenheit before Ispray it on theleaves. For woolly aphis I use it as high as Fahrenheit. For hop-lice(green aphis) Icool to llO 'or 115 Fahrenheit to get the best results.For scale on citrus fruit I use it as hot as Fahrenheit. For vegetablesIcool it to about 110 Fahrenheit. This compound may also be used withgreat advantage in painting chicken-roosts and fowl-houses bydissolvingone ounce of the compound in aboutfive gallons of thicklime-wash.

I claim- An insecticide compound consisting of equal parts of sulfur,resin of pine, soap-powder, sodium oxid, tobacco-stems, castor-oilbeans, pyrethrum-flowers, asphalt-petroleum, fuming sulfuric acid andcommercial phenic alcohol, thoroughly mixed together.
